.Inli'rance March 10, 1933 2 Claims. (01. 226-122) j The invention refers to a cock with a rotary continuous distributor for the machines to fill bottles with a liquid under the pressure of a gas, and more particularly for drawing beer.

In the. filling machine, the filling of the con tainers, after they have been filled with back pressure, is to be had either by means of nozzles filling by 'siphonage, or by means of nozzles filling by gravity but obturated at the right inomerits by valves, or by means of nozzles filling by gravity but obturated at the right moments by interposed cocks. Some of such cocks. include either a conic box provided with the necessary ports and require grinding, or a fiat rotarydis tributor vertically arranged and hindering. the use of a cleaning brush. Thevertical arrangement of the rotary distributor furthermore helps the development of foam which according to its concentration may cause troubles during the drawing operation of beer, for instance.

The cock with horizontal rotary distributor being the object of the present invention avoids the above mentioned disadvantages and is. charac terized inthat: I 1. Between the-filling pipe (vertical or inclined) and the outlet port of the corresponding vat (not represented) is inserted a fiatcircular distributor movable in horizontal rotation and provided with a plurality of outlet ports for the liquid, one of the said ports, at the right moment, being placed exactly in the prolongation of the filling pipe.

2. The distributor is held between two fixed parallel flanges so as to revolve with a tight friction and to take successively the corresponding positions in relation to the various stages required for the full filling operation (filling with back pressure, liquid fall, gas removing,etc. Each fixed flange has a liquid outlet port which is constantly in the prolongation of the filling pipe, in order that when the distributor is in the filling position, all the outlet ports are in connection and stand in the prolongation of the filling pipe, thus allowing a cleaning brush to go through the whole pipe and all the outlet ports.

3. In order to minimize both the amplitude and speed of the distributor rotation, the same is provided with a plurality of a similar series of the ports necessary to the various stages in relation to the full filling operation.

Another characteristic of the cock of the invention is to be found in the fact that for the establishment of the back pressure into the bottle, the portion of the filling pipe is used instead of the returning foam tube. For this purposethe revolving distributor has ports provided into milled parts which allow the air under pressure to go through the down pipe of the vat into the beer outlet pipe.

I Thus is avoided, on the one hand, the driving away of the foam eventually remaining into the back pipes together with the pulverization of the said foam which may originate the emulsion of the beer at the right moment that the bottle is leaving the filling nozzle, and also, on the other hand,'contrary to other known nozzles, the need to arrange into the beer down pipe a second pipe destined either to establish the back pressure or tothe foam returning, and the chief disadvantage of which is to reduce the passage section of the liquid and to bring about a lost load.

Fig. '1 shows in vertical section the cock arranged according to the invention, this section being taken along the line I-I of Fig. 2, and the hole 30 of this figure brought back over the channel l4.

Fig. 2 shows in halfpart along the line II-II a plan View of the distributor and a horizontal section of the lower flange.

Figs; 3 and 4 refer to a similar but modified device. i Figs. 5 and 6 are details of Figs. 3 and 4. In l;h e"1QWer pa,It of the beer vat (not represeated), a" boss I receives, for each drawing post, a fiange 2 in which are provided the channels of back pressure 5, liquid inlet 3 and for previous gas removing 4. The channels 4 and 5 are arranged on the same circumference as their relative channels 5', 4'. Parallel to the flange 2 is a chamber 6 in two parts 1, 8. The part 1 is centered with the flange 2 by a bearing 9 entering a recess ID. The wall 1 has also the pipe l4 and channels 4 and 5 identical to 3, 4, 5 of the fiange 2 and similarly arranged. These channels 4', 5 are in connection through a circular chamber ll limited by a washer l2 bearing a foam returning pipe l3. Within the pipe I3 is provided a concentric outlet pipe M for the liquid, the end of the said pipe being fastened in the wall 1 of the chamber 6. The washer I! together with its packing joint l5 are held by the nut 16 screwing in the tapping cut out into a recess I! of the wall 1.

The size of the chamber the nut ill on the shaft 6 is controlled by [9. This nut I 8 controls the lateral movement of the lower part 8 of the chamber 6 in regard to the wall 1.

-Pins 20, 2| fasten the axis l9 to the flange 2 and chamber 6. The lower part of this last one allows the concentric pipes I3, M to go through.

by the nipple 22 in the packing joint 25 the filling opening of through it and allow it to connect in right line,

the relative channels 4, 5, 3 of the flange 2 and those of the chamber 6.

The tightening of the distributor 24 and flanges is to be had by screwing the nut l8 on the axis l9.

The operation of the device is as follows: The distributor is driven by the teeth 26 in a continuous rotary direction by the revolving motion of the machine bringing the bottles into the due position for drawing, that is with the bottle risen up to the joint 25 and containing the filling pipe I4. In the closed position, one of the T shaped chambers H of the distributor 24 is over the channels 4 5' and pipe I4. The distributor revolving in the direction of the arrow brings the hole 28 in connection with the hole 5, thus allowing'the vat pressure to pass into the bottle through the chamber l I and return pipe 13. The distributor is kept on revolving to bring the hole 30 in ,front to thejpipe l4, and the hole 29 in front to the hole 4. In this position, beer is running owing to gravity from the vat into the bottle in a perfect right line. As foam is produced, it runs away through the pipe l3, chamber ll, holes 29 and 4 to come back to the vat, going through a pipe opening over the level of the liquid. The distributor goes on, revolv-' ing to obturate holes 3, 4 and 5, but the pipe l4 being full of beer that cannot run out andin order to avoid same being lost drop by drop when removing the bottle, the chamber H at the moment the bottle is moved away allows the atmospheric air to enter through the pipe l3, chamber H holes 28 and 29 into the pipe l4.

Figs. 3-6 inclusive show a modified form of the present invention for the use of certain liquids which might give trouble during the drawing operation because of the gas contained therein. In order to overcome this possibility, the modified comprising a flat chamber formed in its lower form of the drawing cock eliminates the return pipe H! of the preferred type and has a distributor with ports 30 formed therein for opening the delivery passages 3 and I4. However, chambers 28 are formed in the lower face of the distributor and these are connected to passageway 5 of the upper flange 2 at the desired time by the ports 28. The back pressure from the gas of the liquid being drawn is taken from the channel 4 into the central supply pipe l4 by way of the port 28 to chamber 28'.

Having now described the object of this invention and in which manner same is to be performed,

'what I claim is:

1. A cock for drawing liquids under pressure rotary distributor, a pair of flanges having said distributor rotating therebetween, said distributor having a plurality of ports and chambers formed therein, said flanges each having a plurality of ports formed therein, said lower flange having a delivery pipe connected to one ofv said ports, said lower flange having a face and connected to a pairvof said ports, a pipe having said delivery pipe therein and connected to said chamber of said lower flange, and said distributor rotating so that said ports and chambers of said distributor and said ports of said flanges will be aligned at desired periods of the rotation of said distributor for performing the various stages for the purpose set forth. v I
